Try to let how your husband behaves wash over you for now I learned the hard way that my husband was never going to support me in the way that I felt that he should. I almost ended my marriage 3 weeks after my mum died it was a horrific time but prior to my mum passing away I was considering leaving anyway and after she was gone I felt that I needed to continue with my plan but I was in no fit state to make any such decisions.
I wouldn't bother if your husband is in the huff about last night if he's that bothered then tough s**t. Harsh I know but he's a big boy he will get over it your primary focus right now is looking after yourself and your mum and allowing yourself to greive the loss of your dad in any way that you seem fit. I often cry alone at home and my husband is in the next room or sometimes he's in the room and doesn't notice or if he does notice then he still asks 8 months on what's wrong with me. That really bugs me and all I have to now is "am crying for obvious reasons". Why can he not just know why am crying it doesn't make any sense why he keeps asking me the same question but probably be doesn't know what else to say.
I hope things get better in your relationship. We are starting couple counselling soon. I owe it to my kids to try to save our marriage I don't want them being upset if we split so we will see how that goes.
About work if ur not ready then you can call your GP to be signed off. I was off nearly 5 months and when I returned I couldn't go back to my old job so I got medical redeployment for 6 months it has help get me back to work.
Take care x
